Definitions
- the present invention relates to a character processing apparatus for outputting character data as in a liquid crystal display unit, a CRT display unit, or a printing unit (e.g., a laser beam printer, an ink-jet printer, and a thermal printer).
- a character processing apparatus for outputting character data as in a liquid crystal display unit, a CRT display unit, or a printing unit (e.g., a laser beam printer, an ink-jet printer, and a thermal printer).
- the width D i allotted to the ith character includes a predetermined value m added to the start and end of each character width C i , respectively, thereby obtaining equal character shift amounts, as shown in FIG. 8.
- FIG. 9 shows an example wherein a predetermined value n is added to the start and to the end of each character width of each of the characters " " (/a/), “ “ “ (/i/), “ “ “ (/no/), and “ “ “ (/ji/), and the resultant characters are output in the same manner as in FIG. 8.
- unnatural spaces are typically formed between the characters, depending on the combination of characters.
- character box 91 is moved so as to overlap with box 90 by a distance l1
- character box 92 is moved to overlap with box 91 by a distance #2, and box 93 is not moved, thus performing kerning. Kerning is performed manually such that a character shift amount is adjusted character by character. Alternatively, kerning is performed automatically such that combinations (kerning pairs) of all characters requiring kerning and pair shift amount adjustment data are prepared in advance.
- a character processing apparatus wherein distances between character patterns and character sizes including space portions of the respective character patterns are stored, a minimum distance between adjacent character patterns is calculated and is compared with a predetermined value, and the distance between the adjacent characters is adjusted when the minimum value is larger than the predetermined value, thereby automatically adjusting the spacings between characters.
- FIG. 1 is a block diagram showing a schematic arrangement of character processing apparatus according to an embodiment of the present invention
- FIG. 2 is a detailed block diagram of a character data unit shown in FIG. 1;
- FIG. 3 is a flow chart showing a control sequence of the character-processing apparatus shown in FIG. 1;
- FIG. 4 is a detailed flow chart of step S4 shown in FIG. 3;
- FIG. 5 is a view showing a relationship between a character pattern and a shift amount
- FIG. 6 is a view for explaining an interval between two adjacent characters in units of segments
- FIG. 7 is a view showing a character string when a character shift amount is a full-size fixed pitch
- FIGS. 8 and 9 are views showing character strings when the character shift amount is a proportional pitch.
- FIG. 10 is a view showing a character string obtained after kerning of the embodiment of the present invention.
- FIGS. 1 and 2 are block diagrams showing an arrangement of a character processing apparatus of the embodiment of the present invention.
- a host computer 1 of an external device outputs print or display data to a character processing apparatus 2.
- the print data sent from the host computer 1 is supplied to a data receiver 3 of the character processing apparatus 2.
- a data analyzer 4 analyzes the data received by the data receiver 3 or input through a keyboard 10 (to be described later) to determine whether that data is print (display) data or other data. Of all data analyzed by the data analyzer 4, only print (display) data is processed by a data processor 5, and its detailed operation will be described later with reference to FIG. 3.
- a character data unit 6 stores data related to characters, and its detailed arrangement will be described later with reference to FIG. 2.
- data other than the print (display) data is processed by an instruction executor 7.
- An output buffer 8 temporarily stores the output data from the instruction executor 7 in the form of pixel data and outputs it to a character output unit 9.
- the character output unit 9 comprises a display unit for displaying data from the output buffer 8 or a printing machine (printer) for printing this data.
- the keyboard 10 includes numeric keys, letter keys, and the like and can set a desired kerning coefficient (to be described later).
- FIG. 2 is a diagram showing a detailed arrangement of a data structure of the character data unit 6.
- the character data unit 6 consists of a character 1 code data section 11, a character pattern data section 12, a shift amount data section 13, and a kerning coefficient data section 14.
- the character code information section 11 stores codes of the respective character data.
- the character pattern data section 12 stores a plurality of character patterns.
- the shift amount data section 13 stores shift amount data of the respective character patterns stored in the character pattern data section 12.
- the kerning coefficient data section 14 stores kerning coefficients. This section may store reference kerning coefficients or values set at the keyboard 10. The kerning coefficients may be stored in units of characters or lines.
- the shift amount of character “F” in FIG. 5 is shown in a rectangle represented by the shift amount for character "F", termed a shift bos.
- the character can be represented by numbers, respectively representing the horizontal length of one horizontal slice, or segment of the character, and distances of the segment between the character patterns. For each non-zero segment, there are, as shown, two respective distances respective 21 and 22 to the side boundaries of the shift box.
- the character data unit 6 stores character patterns and shift amounts in correspondence with character codes. When a character code is input from the data processor 5, the character pattern and the character shift amount which correspond to this input character code are output from the character data unit 6.
- FIG. 3 is a flow chart showing a control sequence of the character processing apparatus 2 of this embodiment.
- a program for realizing the flow chart is stored in a ROM in the data processor 5.
- a printer is exemplified as the character output unit 9 in the following description.
- step S1 data sent from the host computer 1 and received by the data receiver 3 or data from the keyboard 10 is taken in and analyzed by the data analyzer 4. It is checked in step S2 whether the input data is print data. If NO in step S2, the flow advances to step S3, and an instruction is executed by the instruction executor 7. However, if YES in step S2, the flow advances to step S4, and the character data is read out from the character data unit 6. At the same time, the shift amount is read out from the shift amount data section 13.
- the data processor 5 performs data processing using the read-out data and writes the processed data into the output buffer 8.
- step S5 It is determined in step S5 whether character printing is to be performed. If YES in step S5, the flow advances to step S6. If NO in step S5, the flow returns to step S1. In step S6, the contents of the output buffer 8 are read out and sequentially output to the character output unit 9, thereby displaying the processed data at the character output unit 9. It is determined in step S7 whether character output processing is completed. If NO in step S7, the flow returns to step S1.
- FIG. 4 shows a detailed content of step S4 in FIG. 3 and best illustrates the characteristic feature of this embodiment.
- step S11 and S12 of FIG. 4 the first character pattern data C1 and the first shift amount data C1 set are read out from the character pattern data section 12 and the shift amount data section 13, respectively. Of these read-out data, only the character pattern data C1 is written into the output buffer 8 in step S13. It is then determined in step S14 whether the next adjacent character C2 is present. If YES in step S14, the flow advances to step S15. Otherwise, the flow advances to step S28.
- step S15 It is determined in step S15 whether a kerning instruction is included in the data to check if a flip-flop F1 in the data analyzer 4 is set. If it is determined that the flip-flop F1 is set and kerning is to be performed, the flow advances to step S16. Otherwise, the flow advances to step S26.
- step S16 a kerning coefficient K is read out from the kerning coefficient data section 14 and stored in a memory m1 in the data processor 5.
- step S17 "0" is set as the value of a segment number n, and "1,000” is set as an initial value of a distance between two characters, for each segment. These values are respectively set in memories m2 and m3 in the data processor 5.
- step S18 the value of the segment number n is incremented by one.
- step S19 a distance C1max from the end of the character pattern C1 to the beginning of the shift amount character box in the designated segments is detected.
- step S20 a distance C2min from the end of the adjacent character pattern C2 to the end of the shift amount character box is detected.
- step S21 The values detected in steps S19 and S20 are added to each other by an arithmetic section PR in the data processor 5 to obtain a distance e between the adjacent characters on a given segment.
- step S22 the distance e is compared with the distance d between the adjacent characters of the immediately preceding segment. If d>e, then d is set equal to e. It is determined in step S23 whether processing of all segments is completed. If NO in step S23, the flow returns to step S18. Otherwise, the flow advances to step S24.
- step S24 the arithmetic section PR in the data processor 5 compares the predetermined kerning coefficient K with the distance d. If the value of the distance d is smaller than the coefficient K, the distance between the two adjacent characters is kept unchanged. For this purpose, the flow advances to step S26. Otherwise, the flow advances to step S25.
- step S12 If a distance between the two adjacent characters is smaller than the kerning coefficient K and kerning cannot be performed, the value of the shift amount C1 set in step S12 is kept unchanged. If kerning can be performed, the value (d-K) is subtracted from the amount C1 set to obtain a new amount C1 set. In step S26, the new shift amount C1 set is written into the output buffer 8.
- step S27 the character C2 is set as the character C1, and the flow returns to step S11.
- step S14 When no adjacent the next character is present in step S14, the flow advances to step S28 and determine whether kerning is completed. If NO in step S28, the flow returns to step S11. However, if YES in step S28, all the operations are completed.
- step S24 condition d>K is satisfied.
- character codes, character patterns, and shift amounts are stored in the character data unit 6, and the distance between the character pattern and the shift amount box on a given segment is obtained by a calculation.
- distances between the character patterns and the shift amount boxes may be stored in the character data unit 6 for each character pattern. In this case, in steps S19 and S20 of FIG. 4, distances C1max and C2min between the character pattern and the shift amount box of the designated segment are read out from the character data unit 6.
- FIG. 5 shows only horizontal distance data of the letter "F". However, if vertical distance data of characters are provided, kerning can be applied to vertical composition of Japanese characters and the like in addition to horizontal composition (in, e.g., European languages).
- Extraction of the values of distances between two adjacent characters need not be performed for all segments. Instead, such extraction can be performed for a limited number of segments.
- Kerning can be performed for all combinations of user's definition characters in addition to Japanese characters, characters of any other languages, and other symbols.
- values of distances between the character patterns and the character sizes including the space portions of the character patterns are stored, a minimum distance between the adjacent character patterns is obtained at the time of character output and is compared with a predetermined value, and the distance between the adjacent characters is adjusted when the minimum distance is larger than the predetermined distance, thereby automatically adjusting the character spacings.
